From the Guidelines
Remdesivir (RDV) for COVID-19 treatment is administered intravenously in a hospital or healthcare setting, with a standard adult dosing regimen consisting of a 200 mg loading dose on day 1, followed by 100 mg once daily for the subsequent days of treatment. The total duration of therapy depends on disease severity:
- 5 days for hospitalized patients not requiring invasive mechanical ventilation or ECMO (extracorporeal membrane oxygenation),
- which can be extended to 10 days if clinical improvement is not observed, as suggested by the American College of Physicians 1. For patients with severe COVID-19, the effectiveness of a 10-day course of remdesivir in reducing mortality and time to recovery may not vary by age, sex, or race 1. Remdesivir works as an antiviral medication by inhibiting viral RNA-dependent RNA polymerase, thereby preventing viral replication. The medication requires dose adjustment for patients with renal impairment (eGFR <30 mL/min) and should be administered over 30-120 minutes to avoid infusion-related reactions, as recommended by the FDA 1. Patients should be monitored for potential side effects including elevated liver enzymes, nausea, headache, and hypersensitivity reactions during administration. It is essential to assess kidney and hepatic function at baseline and during treatment, and to discontinue the use of remdesivir if alanine aminotransferase levels increase to >10 times the upper limit of normal or if alanine aminotransferase elevation is accompanied by signs or symptoms of liver inflammation 1. The decision to initiate treatment with remdesivir in hospitalized patients with COVID-19 should be based on clinical judgment, considering the balance of benefits and harms, as stated in the practice points from the American College of Physicians 1.

From the Research
Administration of Remdesivir for COVID-19 Treatment
- Remdesivir is administered intravenously, with a 200 mg loading dose on day 1, followed by a 100 mg maintenance dose daily for up to 9 days 2.
- The treatment is recommended for hospitalized patients with COVID-19, with or without supplemental oxygen requirement, as well as nonhospitalized patients with COVID-19 who are at high risk of progression to severe disease 2.
- Remdesivir has been shown to improve survival and disease progression in various patient populations with COVID-19, across a spectrum of disease severity and SARS-CoV-2 variant periods 2.
Dosage and Treatment Duration
- The standard dosage of remdesivir is 200 mg on day 1, followed by 100 mg daily for up to 9 days 3.
- The treatment duration may vary depending on the patient's condition and response to treatment, but it is typically up to 9 days 3.
Combination Therapy
- Remdesivir has been studied in combination with other antiviral agents, such as interferon beta-1a, lopinavir/ritonavir, and ribavirin, but the effectiveness of these combinations is still being researched 3, 4, 5, 6.
- Some studies suggest that combination therapy may be beneficial in certain patient populations, but more research is needed to confirm these findings 3, 4, 5, 6.
